The invention belongs to the cross technical field of deep well mine filling and energy recovery, and particularly relates to a deep well filling pressure reduction and graded pressure energy recovery power generation system, an energy efficiency monitoring method and an operation control method. Comprising an earth surface filling preparation station, a filling vertical pipe, a decompression chamber, a first-stage coupling rotational flow driving device, a second-stage coupling rotational flow driving device, a pressure stabilizing buffer tank and a tail end filling working face. The earth surface filling preparation station conveys slurry into the pressure reduction chamber through the filling vertical pipe, the slurry is conveyed to the first-stage coupling rotational flow driving device through pressure reduction in the pressure reduction chamber, and the first-stage coupling rotational flow driving device drives the first-stage permanent magnet generator to generate electricity. The slurry is conveyed to a secondary coupling rotational flow driving device through a transition pipe after coming out of the primary coupling rotational flow driving device, and the secondary coupling rotational flow driving device drives a secondary permanent magnet generator to generate electricity; the slurry flows out of the secondary coupling rotational flow device and then enters the pressure stabilizing buffer tank, and then is conveyed to a tail end filling working face through the pressure stabilizing buffer tank.

The utility model discloses a frame for a 1.5 kV direct-current circuit breaker, and belongs to the technical field of loading and transferring. The frame comprises a frame body, a rolling shaft protective cover is arranged at the bottom of the frame body, wheel covers are fixedly connected to the two sides of the rolling shaft protective cover, the wheel covers are arranged on the two sides of the bottom of an extension table, and a rolling shaft is rotationally connected to the middle of the rolling shaft protective cover; the two sides of the rolling shaft penetrate through the wheel cover, then the outer side of the rolling shaft is fixedly connected with wheels, a speed sensor, a driving assembly and an energy recovery assembly are arranged on the outer side of the rolling shaft, the speed sensor is located on one side of the wheel cover, and the energy recovery assembly is close to the position of the wheel cover on the other side. The driving assembly can stably and efficiently drive the cart to advance or retreat, the stability and safety of the direct current circuit breaker in the transportation process are ensured, through the linkage design of the push-pull rod and the connecting block, a worker can flexibly adjust the driving direction of the cart, and the cart adapts to the complex and changeable transportation environment.

This application relates to a battery communication system and its operation method. The battery communication system is used for communication among several battery cells. The operation method of the battery communication system includes the following steps: In a wireless daisy-chain communication path of the battery communication system, a first wireless communication unit transmits a transmission signal to an adjacent second wireless communication unit via a wireless transmission or coupling method. In the wireless daisy-chain communication path of the battery communication system, the first wireless communication unit and the second wireless communication unit execute an automatic power control program to automatically adjust the output power of one of the first wireless communication units.
